Wireless Charging Comes To The 2018 BMW 530e – Video

4 weeks ago by Mark Kane 30

The ability to factory order wireless charging on the BMW 530e iPerformance is fast approaching, and with that, the German company has gotten a job on  educating its customers on how it works.

The 530e will guide the driver to park over the primary coil on the ground, and as the ignition will be turned off at this point, wireless charging will begin automatically.

The 9.4 kWh battery can be fully recharged wirelessly in about 3.5 hours using 3.2 kW power.

That rate is a little less than the 3.7 kW on-board charger, but the difference is small. And even still, a full charge only nets one ~16 miles/26 km of all-electric range.

We should note that the price of the wireless charging option is not yet known.

In this clip, you’ll learn more about “BMW Wireless Charging”, the technology that allows energy transfer to take place without the use of cables. Wireless charging for the high-voltage battery will be made available as an option for the BMW 530e iPerformance from 2018. The system consists of a base pad with integrated primary coil – which can be installed in a garage, for example, but also outdoors – and a secondary coil integrated in the underside of the vehicle. An alternating magnetic field is generated between the two coils, through which electricity is transmitted without cables or contacts at a charge rate of up to 3.2 kW. This form of power supply to the high-voltage battery is extremely convenient for customers and involves a charging time of around three-and-a-half hours.

    It’s good, but looks a bit of a pain to get it lined up. Maybe if the pad was a little bigger it would not be something you would have to think about at all but it’s an improvement.

      I’d rather plug in ! There is a lot of wasted electricity charging this way . This is “not” the economical way to go.. But, I guess if you own a BMW it doesn’t matter ….. lol….

      1. Ricardo says:

        Right, the only brand you can possibly say good things of is the economical way to go, sure

        1. L'amata says:

          Truly I tell you., I wouldn’t want this so called feature for free. Think what you will ..But, No Thanks !

      2. john Doe says:

        These will be everywhere, and I’m sure Tesla also will have their version.

        I saw these from 3 brands tested last winter, and they worked fine – even covered in ice and snow.

        When placed in a parking lot, it’s just to park – and the car will start charging.
        Could not be easier.

        Cars will tiny, normal and larger batteries will benefit from the easy charging. The smaller the battery, the more often you will have to charge. This would be a benefit for those who have to charge often.

        There is only a minor loss in electricity – and if you own an EV you can afford it. If not, walking is healthy..

    Big deal. Wireless charging is just a gimmick. All transformers are built this way since day one! Bbigger battery and fast charging is much more difficult!

    1. Warren says:

      Well, it is a big deal for a mainstream OEM to be one of the first out with this technology in this current crop of plug ins. I don’t know of many others offering it right now when there is so much focus on electrification.
      Yeah my phone has wireless charging, as does my Sonic Care toothbrush. So what. Does my tooth brush or phone charge my car when I park it??

    2. Tom says:

      It answers the robotic plug in that some are working on. You can have a parking garage or parking lot and the car can auto valet park itself and plug itself in

    3. Bill Howland says:

      Well, Dan I suppose for most people its not a great revelation, but for those with Arthritis or older drivers (seems to be they’re the only ones who can afford the pricey BMW’s anyway), the wireless charging option is a painless way of refueling the car. Yes there is an efficiency hit, but those with the coin to purchase a new BMW won’t worry about the electric bill anyway.

      1. MikeM says:

        Hats off to Bill H for being the first (approx.) to say something unreservedly positive about wireless charging!

        Consider this:
        Your expensive PHEV with its rinky-dink tiny battery probably needs to be charged, without fail, once or twice a day if you want to keep it working largely in BEV mode.

        If your charging connection is outside your house, you must be out there religiously in the dark, the cold, the rain, the snow, the ice, the . . er. . splutter.. er . and other stuff . . etc.
        And bears. Don’t forget the bears. ( O.K. Raccoons, feral cats, whatever).

        Those who speak derisively of it only taking a couple of seconds to plug in/out must never have tried it under such conditions.

        That said, the small-battery PHEV owners along with the aged/infirm and a handful of frequent-long-range BEV drivers seem to me like the ONLY truly worthwhile demographic for this technology.

        My (hypothetical) Tesla Model3 only needs charging weekly or so in regular use. So I can put up with those agonising plug/unplug sessions once in a while.

        Check out Evatran at pluglesspower.com for more insight into wireless charging for Leaf, Volt, Model-S etc. Those folks have been at it for a couple of years now. (No I have no connection to them).

          You risk of looking silly trying to defend wireless charging that way. Plugging in is as easy as plugging your phone but without additional power losses. Areas where the cable pose liability are prime cases. Indeed there are uses for it but comfort should not be one, we are not that lazy.

          1. MikeM says:

            “Plugging in is as easy as plugging your phone”

            Well I never realized that. Silly me!

            I stand connected.

        2. john Doe says:

          We have a few people at work with PHEVs, and they keep it in the charger when they sleep, and get a warm/cold fully charged car when they wake up, and drives electric to work – without the ICE starting at all.
          They keep it plugged in during the workday, and get a warm/cold fully charged car when they leave for home. All electric drive home..
          But they say that when they need to drive their kids to some sports activities after dinner – the car battery in not full, and the ICE will normally start during the trip, at least in the winter.
          But they fill their tank once a year or so. Unless they also use it for longer trips.

          I see the use of a PHEV (at least in a country with very high gas prices and cheap electrisity), but the battery in normally just 1/2 of what a PHEV should be fitted with.

          With wireless chargers coming, I think they have the option to charge when they’re shopping, at the gym and at whatever else they do after work. As long as they follow a standard. I have only seen this fitted a few month back, outside a library. But I’m sure it will be more common.

          With my use (drive an i3 or a Zöe as a company car), I can just plug in at night, and I’m ready for a week. But it would be easier to just park, and let it charge automatically.

          I think that wireless charging will be standard on all EVs. I guess they should have a normal charging port as well.

    The battery of this car is so tiny you could probably charge it with a wireless phone charger 😀

    1. L'amata says:

      Good One! I love it! Funny as it is, Ur probably not too far 0ff…….lol…..

      1. Warren says:

        Actually it is really far off. A wireless phone charger is generally under 10 watts. The BMW charges over 3000 watts. So I guess if you want to get over 300 phone chargers and spend the time to make it work, have at it! Meanwhile you will have something that takes up more space and is probably even more inefficient.

        1. L'amata says:

          Ur Taking this too too serious . Have some fun with it ! It’s Okay…lol…

  4. notting says:

    >13% = small difference?! EV are so efficient blablabla and then obviously throwing away >13% is ok?! (can’t explain that to myself in an other way)

    And what standard is used? Is that BMW proprietary, so completely useless when not at home?

    notting

    1. Warren says:

      Where did it say there is 13% additional of wasted energy? Do you know what the actual input power vs output power is of this inductive charger? If not, how did you come to your calculations. I must have missed where they stated the 13% greater inefficiency. You certainly can’t deduce efficiency just by the lower output of the charging coil.

      Although this might not be an agreeable technology for you, Energy.gov website seems on board with this:

      https://energy.gov/eere/videos/wireless-charging-electric-vehicles

      1. Ben says:

        Might be even more energy loss than 13%. But than again it will still be less kWh/mile than your model s. Think its good for lazy people, as this creates high usage of the battery for phevs, which is the best solution for a lot of people in the near future.

        1. Rich says:

          I don’t agree with your dig on Model S efficiency or labeling users of wireless charging “lazy”.

          I agree, anything resulting in more electric miles driven is a good thing.

      2. notting says:

        There’re also governments which say/said like rechargeable batterys with Cadmium (very bad for peoples health) are great (especially before NiMH) or nuclear power plants are great because of no CO2…

        notting

    2. mustang_sallad says:

      There is a standard, still in development, but getting close to finalized. SAE J2954, most major manufacturers are involved.

      If you go from $5 a day in gas to $1 a day in electricity, will it really make a difference if it’s $1.15 instead? The efficiency isn’t the problem, it’s the cost of the extra equipment and installation in your driveway, a couple thousand dollars at this stage. It’ll start off on luxury cars like this, just like many other convenience features.

      1. notting says:

        That’s not answering my question. Who says BMW is using that and not something proprietary?

        And the next thing in your posting is that “if”. At first, it completely ignores other costs like much higher prices when buying the car, maintenance (Tesla’s talking about costs nearly like for my ICE), infrastructure at home for charging, etc. – which are usually much higher.
        And second, if an EV (comparable to a certain ICE car) only needs 25kWh/100km when I’m driving to work (mostly ca. 130km/h) and my current gas engine car consumes 8l/100km, it doesn’t even cut the pure energy costs by half – and Diesel is much cheaper than gas, in l/EUR and l/100km (like 15Mm-20Mm/year it’s cheaper incl. buying, maintenance and taxes).

    Fantastic! Any EVs without wireless charging option will be left in the dustbin of history.

    1. L'amata says:

      I really super doubt that… l m a o………..

  6. Lawrence says:

    Has anyone done a test to see if Inductive charging at this amplitude is a health risk? Perhaps low kW chargers have a minimal risk, but considering that charging rates of 10kW will be the norm, it should be considered. A lot of houses have bedrooms above the garage so all of the EMF may be a health hazard.

    1. Ben says:

      No. Long wavelengths like used for inductive charging are considered safe. The electromagnetic field is closed over a short length and loss with distance is high.

      Otherwise your radio stations in your town or the electromagnetic field of your speakers or electric equipment would have killed you already.

      1. Lawrence says:

        You can’t close an electromagnetic field except through shielding. It’s close in proximity, but any break in shielding means a substantial amount of EMF leakage.

        Remember the first law of thermodynamics?
        Where do you think that 12% energy loss vs the hardline goes? It goes into the immediate surrounding.

        I don’t have speakers pumping out 3200 watts for 3+ hours each day in my garage. 300 watts into the average speakers already have you at over 120dBA at 10 feet.

    From plugless’s own FAQ:

    Plugless is ~12% less efficient than corded L2 30amp 240V charging systems and ~7% less efficient than corded Level 1 charging systems
